Few days before he'd planned to announce how to kill someone with a pacemaker remotely...There's been talk of that being possible for years but to my knowledge Barnaby was the first to claim he could demonstrate it(I'd put money th a t tech is already in CIA hands). Interesting his death came shortly after Michael Hastings and his (possibly) hacked car. Crazy tech available right now, were in not for Snowden the public would still be in the dark about how advanced the NSA blanket collections and archives are.
